NEW YORK -- America needs to be at least one technical generation ahead of any adversary when it comes to satellite-based navigation, U.S. President Joe Biden's first defense budget request notes, asking for $1.8 billion to bolster the Global Positioning System.
A portion of that funding will go toward hardening GPS signals against jamming so that fighters, ships and missiles can position, navigate and time their activities even when the enemy tries to disrupt them.
